Phase II Study Assessing the Efficacy and Safety of Lenvatinib for Anaplastic Thyroid Cancer

• Status: Completed
• Trial end date: 2020-03-20
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this phase Ⅱ study is to assess the efficacy and safety of lenvatinib for anaplastic thyroid cancer patients who are diagnosed as unresectable. The total duration of the study will be 30 months. All patients will start administration of lenvatinib within 1 week of enrollment and receive the study drug 24mg orally once daily at almost the same time. 1 cycle consists of 4 weeks. Treatment term starts on the day 1st of drug administration of cycle 1 and administration will be continued until patients meet withdrawal criteria. Safety and efficacy assesment will be conducted on a regular basis during the trial. Tumor evaluation will be conducted at 4weeks, 8 weeks, 12 weeks, 16 weeks and at every 8 weeks after the 16th week since initial administration. When study drug administration terminated,tests of the drug termination will be conducted within 7 days of withdrawal and final observation will be conducted at 30 days after the last dose. Survival survey will be conducted at follow-up term. After the termination of the study drug, survival follow up survey will be conducted every 12 weeks unless patients withdraw enrollment of this study.
